Whether the application requires single or twin leg configurations, mounting to an overhead anchor, or connection directly to a harness, there are numerous fall protection models to choose from to suit almost any application. 3M™ DBI-SALA® Nano-Lok™ Self-Retracting Lifeline (SRL) with Anchor Hook's smart activating brake system achieves fall clearance as low as 4 feet (1.2 m) while stopping a fall within inches and providing more protection at low heights. In addition, tension is always kept on the lifeline helping to reduce dragging, snapping, and trip falls. These features are key safety improvements and provide the user with the comfort and support required to get the job done right.
